Shareholders
3
Three shareholders are currently on record for ARCELLX, INC., reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.
The largest of these is Vanguard Group Inc, holding 8% — the largest recorded stake — followed by iShares Trust-iShares Russell 2000 ETF at 1.7%; the remaining 1 shareholder shown holds smaller stakes.
Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.
